Equation for circumference is c = 2(pi)r

r = 1/2(d)

d = 20

So…. r = 1/2(20) = 20/2 = 10

Going back to circumference equation

c = 2(pi)(10) = 2(3.14)(10) = 62.8

Answer:

Step-by-stexplanation:

The formula for circumference is C=2πr

C (circumferece) divided by 2 equals your r (radius) wich is 10

plug in 10 for R use the following formula (c=2πr) to get your answer
you should get 62.83185 which rounds to 62.8

Your welcome :)

For a given input value b, the function f outputs a value a to satisfy the following equation. 4a+7b=−52 Write a formula for ) f

Sergio [31]

Answer: Our required formula becomes :

$a=f(b)=-13-\frac{7}{4}b$

Step-by-step explanation:

Since we have given that

$4a+7b=-52\\$

We need to write a formula for f(b) in terms of b So, it becomes

$4a=-52-7b\\\\a=\frac{-52-7b}{4}\\\\a=\frac{-52}{4}-\frac{7b}{4}\\\\a=-13-\frac{7b}{4}$

Hence, our required formula becomes :

$a=f(b)=-13-\frac{7}{4}b$
